To all whom it may concern:

Be it known that LCHARLES A. BULL, a citizen of the United States, residin at Albion, in the county. of Boone and tate of Nebraska, have invented certain new and useful Improvements in Automobile-Locks;

. and I do declare the following to be a full,

' clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

a This invention relates to improvements in safety devices and particularly to an im-. proved lock for gasolene engines used on automobiles'and various other places where the engine and associated parts are adapted to move from place to place.

The primary object of this invention is to provide a locking valve for internal combustionengines, the same being extremelysimple in construction, thereby decreasingto a minimum the cost of manufacture.

Another object of the invention is to provide a. locking valve which will prevent the operation of the engine when the valve is in locked position, the location thereof being such that the removalor tampering of the valve cannot be done with the hope of starting the engine.

. A still further object in view is to provide a locking valve whichmay be locked independently of the ordinary butterfly valve locatedin the intake manifold.

- With these and numerous other objects in view, my invention resldes 1n the novel features of construction. and the combina tion and arrangement of the several parts as William hereinafter more fully described and pointed out in the specification and claims.

"In the accompanying drawings:

Figure 1 is a fragmental sectional view ofan intakemanifold and carbureter with my locking valve applied;

Fig. 2 is a horizontal section on the plane of line 22 ofFig. 1;.

Fig.- 3 is a vertical section on the plane of tline 3= 3 of Fig. 2;

4a is a horizontal section, on the plane in the outer flat face 7 of a laterally extend- Fig. 5; 1s a sectional view on the plane of line 5- 5 of Fig. 3;

I Fig. 6 is a top plan view of. the casing wh ch carries the locln'ng valve;

- Fig. 7 1s a'detail perspective view of the lock and I disk supporting shaft ;v and,

8 is a top plan view of'the lock. Similar numerals of reference are used to indicate corresponding parts in the several vlews.

Reference is now had to the drawingsin which the usual manifold 1 is shown provided with the short connecting pipe 2 and the carbureter 3 having the ordinary gas control butterfly valve 4 which is operated by a rod connected to the arm 5 on the upper end of the shaft on which the valve is mounted.

The carbureter3 is supplied with gasolene through the pipe 6 and after the gasolene has been carbureted, it passesthrough the passageway in the casing or union 8, through short pipe 2 to the manifold from which it passes into the cylinders;

The casing or union 8 as shown'in the drawings has laterally extending attaching plates or flanges 9 which have threaded ap-' ertures therein adapted to be alined with apertures in contacting flanges 10 on each end of said union and to receive threaded bolts 11 therethroughto secure said union in proper position and suitable gaskets clamped between said flanges'to form a gas tight .joint.

A butterfly valve 12 is rigidly secured to a shaft "13 which is rotatably mounted in what will be termed upper and lower bearings in the casing. or union 8, the aperture forming the upper bearing opening into a large circular recess 14 whose wall is offset at 15, as shown in Figs. 3, 5 and 6, substantially one-quarter of its circumference to form stops 16 and 17 whose purpose will-be hereinafter. described.

Thelock 18 may be of any desired type and its casing maybe formed integral with the union 8 or may be separatetherefrom and be provided with a longitudinally extending lug, or pin 19 secured to its inner.

end and projecting into a socket 19 formed preventing rotation of the j in view of the simple construction, it is readily seen that the manufacturing cost is casing in relation to the union and then having the abutting edges of the lock casing 18 and the union 8 brazed or otherwise secured together.

Extending longitudinally from the inner end of the rotary cylinder 20 of the lock is a flat lug 20 adapted'to be received between the pair of longitudinally extending ears 21 on the upper end of the shaft 13, said ears and lug having alined apertures therein to receive a connecting pin 22, one end 22.

extending into the offset portion '15 of the recess 14 in the union and the other end extending to a point adjacent the wall of the recess.

It will be readily seen that when the butterfly valve 12 is to be opened, the rotary cylinder19 is given a one-quarter turn by the 1 ranged in the feed pipe and bridged the broken part or valve by a*-fiexible tube through which the gasolene readily flows; By positioning the locln'ng valve between the manifold and carbureter, it is seen that removing-or breaking said valve would ren- 35 der' the engine useless, since the gasolene must necessarily pass through the carburetor before entering the manifold.

From the foregoing description of the construction of the operation of my improved automobile lock, the manner of applying the same to use and the. operation thereof will be readily understood, and it will be seen that I have provided a simple and efficient device of this character for carrying out the objects of the invention, and

reduced to a 'Iclaim:j V e A 1. In a device ofth'e class described,'a casing having a passageway therethrough to aline with the passageway in the intake manifold of a gas engine, a laterally extending enlarged portion of said'casing,*said enlarged portion having a circular recess in its outerflat face, a shaft rotatably mounted in upper and lower bearingsin the casing,

- said upper bearing opening through the bot- ,tom 0 'the circular recess, the wall of said recess being offset substantiallyjone-quarter of its circumference to form stops, said shaft having a pairof parallel spaced ears extending longitudinally from the upper end there- .of into the recess, said flat face having a socket therein spaced'to one side of-the circular recess, a lock casing secured to the aforesaid casing and one end abutting the flat face of said enlarged portion, said lock casing having a longitudinally extending lug on its inner end projecting into said socket to prevent rotation thereof, a rotary cylinder in said casing, said cylinder being longitudinally alined with the aforesaid shaft, and having a longitudinally extending lug received between theaforesaid pair of ears, said lug and ears being apertured and receiving a pin therethrou h, one end of said PlILPIO] ectm into the 0 set portion to abut the aforesai stops when the cylinder of the lock is given a one-quarter revolution in either direction, and a disk in said casing secured to the shaft to close the passageway.

2. In a device of the class described, a casing having a passageway therethrough to aline with the passageway in the intake manifold of a gas engine, a laterally extending enlarged portion on said casing, a shaft rotatably mounted in up or and lower bearings in said casing, a loc casing on said enlar-ged portion, a rotary cylinder in said lock casing, said enlarged portion having a circu-. lar recess therein adjacent the inner end of said cylinder, said cylinder having a longitudinally extending lug on its 1111161 end projecting into the recess, the wall of said recess being'oifset substantially one-quarter of its circumference to form stops, said upper bearing opening into the recess, a pair of parallel spaced ears extendin longitudinally from the upper end of sa1d shaft and projectin 'into said recess, said ears receivlng the a oresald lug therebetween, sa1d cars and lugs having apertures therein receiving a pin therethrough to connect the shaft and cylinder, oneendof said -pin projecting into the offset portion, whereby when the cylinder is given a one-quarter revolution in either direction the aforesaid one end of the pin will abut one of the stops to prevent further rotation, and a disk secured to said shaft and adapted to close the passageway.
